Innovations in Unbreakable Glass
As the demand for durable and safe glass continues to grow, various innovations have emerged in the field of unbreakable glass. These advancements have led to the development of shatterproof glass, safety glass, and bulletproof glass.
Shatterproof Glass
Shatterproof glass, also known as laminated glass, is made by sandwiching a layer of plastic film between two layers of glass. This construction enhances its strength and prevents it from shattering into dangerous shards when broken. The plastic interlayer holds the broken glass pieces together, providing added safety and security. Laminated glass is commonly used in automotive windshields and applications where safety is a primary concern. For more information on the benefits and characteristics of laminated glass, refer to our article on the benefits of laminated glass.
Safety Glass
